[0034] The present utility model provides a circulating card issuer.

[0035] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the circulating card issuer includes a machine shell 10, two conveying roller groups 20, an identification module 30 and a main control module. The machine shell 10 has a card storage slot 10a, a card issuing channel 10b and a card outlet 10c that are sequentially communicated; the two conveying roller groups 20 are installed in the card issuing channel 10b and are arranged at intervals; the identification module 30 is installed in the card issuing channel 10b and is located above the two conveying roller groups 20; the identification module 30 is used to identify the cards flowing through the card issuing channel 10b; the main control module is electrically connected to the identification module 30 and the two conveying roller groups 20, and is used to receive the electrical signals sent by the identification module 30 and control the rotation of the conveying roller groups 20.

[0036] The casing 10 is made of high-strength plastic or metal material, having good durability and protective performance. Inside the casing 10, there are three sequentially connected parts, namely the card storage slot 10a, the card issuing channel 10b, and the card outlet 10c. Each set of rollers consists of two rollers, which are installed in the card issuing channel 10b and arranged at intervals. The roller set is made of high-quality materials, having good wear resistance and rotational flexibility. The first transfer roller set 20 is located at the connection between the card storage slot 10a and the card issuing channel 10b, for transferring the card from the card storage slot 10a to the card issuing channel 10b. The second transfer roller set 20 is located at the connection between the card issuing channel 10b and the card outlet 10c, for transferring the card from the card issuing channel 10b to the card outlet 10c. The identification module 30 is installed in the card issuing channel 10b, above the two transfer roller sets 20. The identification module 30 has high-precision identification ability, capable of quickly and accurately identifying the card. The main control module is electrically connected to the identification module 30 and the two transfer roller sets 20, responsible for receiving the electrical signals sent by the identification module 30 and controlling the rotation of the transfer roller sets 20 according to the signals.

[0037] The user puts multiple cards into the card storage slot 10a. The card storage slot 10a is internally designed with an anti-slip device to ensure that the cards will not slide during the card storage process. After receiving the instruction input by the user, the main control module controls the first transfer roller set 20 to start rotating, transferring the bottommost card in the card storage slot 10a from the card storage slot 10a to the card issuing channel 10b. After the card enters the card issuing channel 10b, the identification module 30 identifies the card and sends the identification result to the main control module. The main control module controls the second transfer roller set 20 to rotate according to the identification result, transferring the card from the card issuing channel 10b to the card outlet 10c. The card is output from the card outlet 10c, completing the entire card issuing process.

[0038] Compared with the previous position where the identification module 30 was set behind the three transfer roller modules, the distance between the identification module 30 and the card was relatively long, affecting the identification accuracy of the identification module 30. In this utility model, by setting two transfer roller sets 20 in the card issuing channel 10b, the two transfer roller sets 20 are arranged at intervals, and the identification module 30 is set at the position between the two transfer roller sets 20. With such a setting, whether the card moves out of the card outlet 10c from the card issuing channel 10b or the card moves back to the card issuing channel 10b from the card outlet 10c, the identification module 30 is within the moving range of the card, shortening the distance between the identification module 30 and the card, making it easier for the identification module 30 to identify the entry and exit of the card, thereby improving the accuracy of card identification and ensuring the normal use of the cyclic card issuing machine.

[0039] The identification module 30 is installed inside the card issuing channel 10b and above the two conveyor roller groups 20. Such a layout is conducive to the real-time and accurate identification of the card, making the transmission of the card in the card issuing channel 10b more uniform and stable. This design avoids transmission failures caused by card stacking or uneven rolling, and significantly improves the card issuing efficiency.

[0040] The cyclic card issuing machine adopts the design of a card storage slot 10a, a card issuing channel 10b, and a card outlet 10c that are connected in sequence, making the flow path of the card inside the machine smoother, and greatly reducing the risk of jamming or damage that may occur during the transmission of the card.

[0041] In one embodiment, please refer to Figures 1 to 3 , the identification module 30 includes a mounting plate 31 and a first optical identification module 32. The mounting plate 31 is fixed to the inner wall of the machine housing 10; the first optical identification module 32 is mounted on the mounting plate 31 and is used to automatically identify and convert the text content in the card; the first optical identification module 32 is electrically connected to the main control module and is arranged adjacent to the card outlet 10c.

[0042] The mounting plate 31 is made of high-strength aluminum alloy, with excellent stability and corrosion resistance. The mounting plate 31 is in a flat shape, and its size is designed according to the inner wall space of the machine housing 10 to ensure stable installation. The mounting plate 31 is fixed to the inner wall of the machine housing 10 by four fixing bolts, and the positions of the bolts are evenly distributed to ensure that the mounting plate 31 is closely attached to the inner wall of the machine housing 10, preventing the mounting plate 31 from loosening due to vibrations or other reasons. The first optical identification module 32 is mounted on the mounting plate 31 and is used to automatically identify and convert the text content in the card. The first optical identification module 32 includes a camera, a light source, and an image processing unit. The camera is used to capture the image on the card, the light source provides uniform illumination, and the image processing unit processes the captured image, identifies the text content and converts it. The first optical identification module 32 is electrically connected to the main control module and uses a USB interface to achieve data transmission. The first optical identification module 32 is arranged adjacent to the card outlet 10c, and the specific distance is determined according to the internal space of the machine housing 10 and the card size.

[0043] The present utility model greatly improves the identification efficiency and accuracy of the text content of the card by setting the identification module 30, which includes the mounting plate 31 and the first optical identification module 32. The fixed design of the mounting plate 31 makes the overall structure more stable, which is conducive to the accurate identification of the first optical identification module 32.

[0044] The first optical identification module 32 is arranged adjacent to the card outlet 10c, enabling the card to pass through the identification module 30 more smoothly during the identification process, reducing identification errors caused by card position deviation, and thus further improving the accuracy and reliability of the identification.

[0045] In one embodiment, refer to Figures 1 to 3 , the identification module 30 further includes a second optical identification module installed on the mounting plate 31. The second optical identification module is spaced apart from the first optical identification module 32 and is electrically connected to the main control module; and the second optical identification module is disposed adjacent to the card slot 10a.

[0046] The identification module 30 includes a first optical identification module 32 and a second optical identification module. The first optical identification module 32 is installed on the mounting plate 31, and its position is on the left side of the mounting plate 31. The second optical identification module is also installed on the mounting plate 31, and its position is on the right side of the mounting plate 31, spaced apart from the first optical identification module 32.

[0047] A card slot 10a is provided on the right side of the mounting plate 31. The card slot 10a is used to store various cards, such as identity cards, bank cards, etc. The second optical identification module is disposed adjacent to the card slot 10a, facilitating the identification of the cards stored in the card slot 10a. When the user inserts a card into the card slot 10a, the second optical identification module reads the card information through optical identification technology and transmits the read information to the main control module. The main control module performs corresponding processing according to the received information, such as verifying the validity of the card and reading the card information.

[0048] By adding a second optical identification module on the mounting plate 31, spaced apart from the first optical identification module 32, a dual identification mechanism is formed. This design effectively improves the accuracy and reliability of identification. At this time, the second optical identification module can serve as a backup to ensure the normal operation of the entire system, thereby avoiding failures or accidents caused by identification errors.

[0049] In one embodiment, refer to Figures 1 to 3 , the cyclic card issuer further includes a blocking block 40 installed on one side of the card slot 10a adjacent to the card issuing channel 10b. The blocking block 40 and the bottom wall of the card slot 10a are spaced apart to form a communication port, and the communication port communicates with the card issuing channel 10b; the blocking block 40 is used to limit the positions of multiple cards in the card slot 10a so that the multiple cards are discharged one by one to the communication port.

[0050] The card slot 10a is used to store the cards to be issued and is located above or on the side of the card issuer. The card slot 10a has a bottom wall and side walls. The card issuing channel 10b is located below the card slot 10a and is used to guide the cards to be discharged one by one from the card slot 10a. The blocking block 40 is installed on one side of the card slot 10a adjacent to the card issuing channel 10b.

[0051] The blocking block 40 is located on the side of the groove side wall adjacent to the card issuing channel 10b. A communication port is formed at an interval between the blocking block 40 and the groove bottom wall, and the communication port is communicated with the card issuing channel 10b. The shape and size of the blocking block 40 are reasonably designed to form an appropriate communication port at an interval from the groove bottom wall, ensuring that the card can smoothly pass through the communication port and enter the card issuing channel 10b. The function of the blocking block 40 is to limit the positions of multiple cards in the card storage slot 10a, so that the multiple cards are discharged one by one to the communication port.

[0052] The blocking block 40 positions the cards in the card storage slot 10a, making the cards approach the communication port one by one. When the front end of the card reaches the communication port, the card enters the card issuing channel 10b through the communication port under the action of gravity. The card issuing channel 10b guides the card to the card outlet 10c through two transmission pulley groups to complete the card issuing operation.

[0053] The communication port formed by the interval between the blocking block 40 and the groove bottom wall of the card storage slot 10a effectively communicates with the card issuing channel 10b, ensuring that the cards in the card storage slot 10a can be discharged one by one and orderly to the communication port. Compared with the prior art, this design improves the accuracy and reliability of card discharging, avoids mutual interference between cards, reduces the problem of discharging failure caused by card crossing or overlapping, and thus greatly improves the overall working efficiency of the card issuing machine.

[0054] In an embodiment, please refer to Figures 1 to 3 , an arc surface 41 is provided on the side of the blocking block 40 facing the card storage slot 10a, and the arc surface 41 is bent away from the card storage slot 10a; one end of the blocking block 40 facing the groove bottom wall of the card storage slot 10a is an arc end 42, and the arc end 42 contacts the card.

[0055] The existence of the arc surface 41 can effectively prevent the card from directly colliding with the blocking block 40 when inserted or removed, thereby reducing the possible damage to the card caused by the collision. At the same time, the design of the arc surface 41 also enables the card to slide into or out of the card storage slot 10a more smoothly under the action of the blocking block 40, improving the efficiency and convenience of card access. Secondly, one end of the blocking block 40 facing the groove bottom wall of the card storage slot 10a is an arc end 42, and the arc end 42 contacts the card. This design optimizes the part where the card contacts the blocking block 40, enabling the card to disperse the pressure more evenly when affected by the blocking block 40. The existence of the arc end 42 can not only reduce the possible deformation of the card when under pressure, but also protect the edge of the card to a certain extent and prevent the card edge from being damaged due to friction.

[0056] In an embodiment, please refer to Figures 1 to 3, the recycling card issuer further includes a holding member 50, which is fixed to the inner wall of the card issuing channel 10b, is disposed adjacent to the card storage slot 10a, and is spaced apart from the identification module 30; one end of the holding member 50 away from the inner wall of the card issuing channel 10b is used to support the card flowing through the card issuing channel 10b.

[0057] After the recycling card issuer is started, initialization operations are first performed, including self-checking, calibration and other steps to ensure the normal operation of the card issuer. The operator places the card to be issued into the card storage slot 10a, and the card slides into the card issuing channel 10b under the action of gravity. When the card flows through the card issuing channel 10b, one end of the holding member 50 extends out of the inner wall to support the card and prevent the card from jittering or falling during transmission. The identification module 30 identifies the card and obtains the type and attribute information of the card. According to the information provided by the identification module 30, the recycling card issuer controls the movement of the conveying roller group 20 to push the card out of the card issuing channel 10b to complete the card issuing operation.

[0058] One end of the holding member 50 is connected to the inner wall of the card issuing channel 10b, and the other end extends out of the inner wall for supporting the card flowing through the card issuing channel 10b. One end of the holding member 50 away from the inner wall of the card issuing channel 10b is used to support the card, ensuring the safety of the card during transmission.

[0059] In one embodiment, please refer to Figures 1 to 3 , the holding member 50 is a holding piece, and one end of the holding piece away from the card issuing channel 10b is bent in a direction away from the identification module 30.

[0060] A certain distance is maintained between the bent end of the holding piece and the identification module 30 to ensure that the identification module 30 will not be interfered with when the card passes through the holding piece during card issuing. During actual use, the holding piece holds the card through its bent end to keep it in a specific position, thus facilitating the identification module 30 to identify the card.

[0061] The bending design enables the holding piece to better support the card and prevent the card from shifting due to vibration or other external force factors during transmission, thus ensuring that the card can accurately pass through the identification module 30 and improving the accuracy of identification.

[0062] In one embodiment, please refer to Figures 1 to 3 , the holding member 50 is provided with a connecting rib 51, one end of the connecting rib 51 away from the holding member 50 is connected to the bottom wall of the card storage slot 10a, and the connecting rib 51 is spaced apart from the conveying roller group 20.

[0063] The connecting rib 51 is located on the upper surface of the holding member 50. It is strip-shaped and made of high-strength stainless steel to ensure sufficient supporting force and durability. One end of the connecting rib 51 away from the holding member 50 is connected to the bottom wall of the card storage slot 10a by welding to ensure the firmness of the connection. The connection point of the connecting rib 51 and the bottom wall is located at the center of the card storage slot 10a, which is beneficial to the uniform distribution of force.

[0064] One end of the connecting rib 51 away from the holding member 50 is connected to the bottom wall of the card storage slot 10a. This structural design enables the holding member 50 to transfer the force to the bottom wall of the card storage slot 10a through the connecting rib 51 when an external force acts on it, thus enhancing the overall stability. In practical applications, this design can prevent the holding member 50 from deforming or being damaged during handling or use, greatly extending the service life of the holding member 50.

[0065] In one embodiment, please refer to Figures 1 to 3 , the circular card dispenser further includes a mounting shaft 60 and at least one torsion spring 70. Both ends of the mounting shaft 60 are fixed to the inner wall of the card issuing channel 10b. One end of the holding member 50 is connected to one end of the torsion spring 70, and the other end of the torsion spring 70 is connected to the mounting shaft 60.

[0066] The mounting shaft 60 is arranged on the inner wall of the card issuing channel 10b for fixing and supporting the torsion spring 70. The torsion spring 70 is used to provide a driving force to push the movement of the holding member 50. When the circular card dispenser is working, the torsion spring 70 is subjected to a driving force and generates a torsional movement. The torsional movement of the torsion spring 70 is transmitted to the holding member 50 through the connection point, so that the holding member 50 keeps moving upward in the card issuing channel 10b. When the card moves in the card issuing channel 10b, the holding member 50 can maintain an upward state to more stably support the card, preventing the card from falling down, thereby improving the card issuing stability of the circular card dispenser.

[0067] In one embodiment, please refer to Figures 1 to 3 , the circular card dispenser further includes an electric gate 80 installed at the card outlet 10c. The electric gate 80 is used to block or open the card outlet 10c.

[0068] The design of the electric gate 80 can effectively block the card outlet 10c, preventing the card from accidentally popping out when it is not properly processed, thus avoiding the risk of user misoperation or card loss. The technical effect directly brought by this technical feature is to ensure the safety of the card issuing process and reduce the losses caused by incorrect card processing.

[0069] The automatic control function of the electric gate 80 makes the card issuing process more intelligent and automated. During the operation of the card dispenser, the electric gate 80 can be opened or closed in a timely manner according to the system instructions to ensure that the card is output at the correct time, improving the operation efficiency of the entire card issuing system and the user experience.

[0070] The housing 10 further has a recycling bin 90, which is located below the card issuing channel 10b and is in communication with the card issuing channel 10b. The recycling bin 90 is used to store the cards that need to be recycled.

[0071] The recycling bin 90 is located below the card issuing channel 10b and is in communication with the card issuing channel 10b. This design effectively utilizes the space, making the card recycling process smoother. Compared with the prior art, it has obvious advantages in card management and can better meet the user's needs for card storage and recycling. Secondly, the setting of the recycling bin 90 enables the cards that need to be recycled to be effectively stored, avoiding the scattering and loss of the cards. This design improves the security of the cards, reduces the damage caused by improper storage of the cards, and thus extends the service life of the cards.

[0072] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
